Your local bank will be delighted to assist you with this enquiry (especially first thing on a Monday morning).
For my part... I have mislaid my booklet about early 21st century 'Eastern European Currencies'... but I feel fairly confident that even if £187.78p is a tad over reaching... you should be able to exchange it for at least something.
Perhaps a large box of those delicious Polish sausages, made from steam recovered eyeballs and industrial strength paper.
Mostly only in EU Banks I have some here in Australia and Cannot change them
Can I exchange it? No. But your bank can.
you said its worth 187.78 pounds ...Seems like you know the answer
Can you exchange a 2001 1000 polishy zloty note? Its £187.78 in British pounds but can I exchange it or not thanks....
